So we’re all ending up like Krypton?

I don't think it gets to that level. I do believe the earth goes through a cycle of increased volcanic activity which throws the earth into an ice age every 100K years or so. We're past due...

For the past several hundred years I have noticed a pattern of about 30 year increased volcanic activity and earthquakes, ending with a large volcano, and then a more quiescent period for the next 70 years. Perhaps we will have a big volcano like Tambora (1815), and Katmai (1912) very soon??
